Rick: don't know how many of which models/years of 'Tac's have dowelled necks - not sure what year mine is, but I'd sure hope that at least some of the 'Tac's are not dowelled, but dammit, mine is!

I've noted many a 'Tac w/very decent sound, indeed! It seems like such a cheap trick in an otherwise decent instrument; haven't looked seriously at a 'Tac, no matter how attractive, since.

Mine is an "F-400S" ser #79100822, bought from a flea market dealer, w/a permanent stand, off hwy 59, in Houston abt 8 or 9 yrs ago. May that will help you guess if your's is of similar vintage, & possible the same or similar dowelled construction

Cheers, BK
